A Quality of Life Technology (QoLT) research team at NRRI design and build a QoLT testbed for assessing QoLT products, i.e., highly advanced assistive devices, and prescribing appropriate living environment for the individuals with disability. The QoLT testbed is possible by Focus Group`s participation in user needs analysis, design, and building of the testbed. To design effective and efficient method of prescription and delivery of appropriate independent living environment for the individuals with disability, the QoLT team at NRRI designs a tentative assessment protocol focused on performance and satisfaction, parts of accessibility and usability, and evaluate the tentative protocol for seven months. The tentative assessment protocol for accessibility and usability of assistive devices in testbed environment for independent living of individuals with disability including Spinal Cord Injury (SCI) is designed and verified with outcomes of 15 cases. The tentative assessment protocol is designed by referring Canadian Occupational Performance Measurement (COPM) with ten scale-based scoring and performed by an Occupational Therapist. The 15 subjects are 10 individuals with SCI - seven cervical spinal cord injury, two thoracic spinal cord injury, one lumbar spinal cord injury - and five individuals with stroke - three individuals with left hemiplegia and two individuals with right hemiplegia. 15 subjects are taken surveys before and after living in the testbed from one week up to four weeks, which is a part of the tentative assessment protocol.
